NASHVILLE, Tenn. – Lanes closures are planned on Interstate 40 in west Nashville this weekend to accommodate ongoing construction at White Bridge Road.

As work continues on new fly-over ramps at I-40 and White Bridge, the Tennessee Department of Transportation said the lane closures are necessary to tear out part of a retaining wall and pour bases for new overhead sign structures.

Crews will also be pouring concrete decking on the new ramp from I-40 East to Briley Parkway.

Traffic will be affected in both directions on I-40, beginning at 9 p.m. Friday through 5 a.m. Monday.

Beginning at 10 p.m. both Saturday and Sunday, only one eastbound lane and one westbound lane will be open until near daybreak the following morning.

The $32 million Briley Parkway/White Bridge Road connector project is one of the largest in Tennessee, funded with the use of federal stimulus money.

When complete in August 2011, drivers will no longer have to exit onto White Bridge Road to get from I-40 East to Briley and from Briley to I-40 West, as they do now.
